springboot整合hive-jdbc遇到的坑

问题描述：springboot整合hive-jdbc时，pom文件加入hive-client依赖，eclipse启动，项目正常启动，访问正常。打成jar包放到服务器启动正常，访问报错如下：

org.apache.jasper.JasperException: /views/public.jsp(3,62) PWC6188: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

原因分析：貌似是缺少jstl的jar包，检查后发现自己项目lib里有啊~~~，实际原因：jar包冲突。因为springboot内嵌tomcat，而hive-jdbc也有一堆附加依赖tomcat、jasper的jar（具体没看，大概瞅了一眼）。

解决：hive-jdbc依赖排除一切和自己想要的功能无关附加依赖，具体如下：

	org.apache.hive
	hive-jdbc
	2.3.2
	
		
			org.eclipse.jetty.aggregate
			jetty-all
		
		
			org.apache.hive
			hive-shims
		
		
			jasper-compiler
			tomcat
		
	        
			 jasper-runtime
			  tomcat
		
		
			servlet-api
			javax.servlet
		
		
			log4j-slf4j-impl
			org.apache.logging.log4j
		
		
			slf4j-log4j12
			org.slf4j
		
		
                    tomcat
                    *
                
                
                    ch.qos.logback
                    logback-classic
                
                
                    org.eclipse.jetty.orbit
                    *
                
                
                    org.eclipse.jetty.aggregate
                    *
                
                 
                    javax.servlet
                    servlet-api
                
                
                    org.mortbay.jetty
                    *
                
	

OK，页面访问正常了~
